Description
Verfahren zur Darstellung eines Farbstoffes der Galloeyaninreihe. Es wurde gefunden, dass man zu wert vollen Farbstoffen der Cxallocyaninreihe ge langt, wenn man Gallussäure oder deren De rivate, wie Gallamid, Gallanilid, Gallussäure- ester oder auch Pyrogallal und Abkömmlinge dieser Körper, mit Nitrosoverbindungen se kundärer oder tertiärer aromatischer Amine der allgemeinen Formel:
EMI0001.0011
kondensiert, worin R Wasserstoff, Alkyl, Oxalkyl, Sulfalkyl oder Aralkyl bedeutet.
Die so erhaltenen Farbstoffe können ge gebenenfalls nach den bei der Herstellung von Farbstoffen der Gallocyaninreihe übli ehen Methoden in weitere Derivate über führt werden, zum Beispiel durch<B>Ab-</B> spaltung der Carbogylgruppe, Reduktion zu Leukofarbstoffen, Kondensation mit Mono oder Diaminen oder deren Sulfonsäuren, Die nach diesen Arbeitsweisen gewonnenen Produkte können nötigenfalls noch einer nachträglichen Sulfonierung unterworfen werden.
Die so erhaltenen Farbstoffe zeichnen sich durch eine besonders für Druckfarbstoffe erwünschte vorzügliche Löslichkeit, durch Klarheit des Farbtones und durch gute Echt heitseigenschaften aus.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines neuen Farbstoffes der Galloeyaninreihe durch Kon densation von Gallussäure mit Nitrosodisulfo- äthylanilin.
<I>Beispiel:</I> 17 Gewichtsteile Gallussäure werden in 300 Gewichtsteilen 95 %igem Alkohol heiss gelöst, und in die Lösung werden 51 Ge wichtsteile Nitrosodisulfoäthylanilin einge tragen in dem Masse, wie die Gelbfärbung verschwindet. Der Farbstoff der Formel:
EMI0002.0001
fällt aus. In Form seiner Alkali- oder Am moniumsalze ist er vorzüglich löslich. Er gibt auf Baumwolle mittelst Chrombeize gedruckt sehr gleichmässige, blaue Töne von guter Licht-, Chlor- und Seifenechtheit.
Process for the preparation of a dye of the galloeyanin series. It has been found that valuable dyes of the cxallocyanin series are obtained if gallic acid or its derivatives, such as gallamide, gallanilide, gallic acid ester or even pyrogallal and derivatives of these bodies, with nitroso compounds of secondary or tertiary aromatic amines of the general formula :
EMI0001.0011
condensed, wherein R is hydrogen, alkyl, oxalkyl, sulfalkyl or aralkyl.
The dyes obtained in this way can optionally be converted into further derivatives by the methods customary in the preparation of dyes of the gallocyanin series, for example by splitting off the carbogyl group, reducing to leuco dyes, condensation with mono or Diamines or their sulfonic acids. The products obtained by these procedures can, if necessary, be subjected to a subsequent sulfonation.
The dyes obtained in this way are distinguished by excellent solubility, which is particularly desirable for printing dyes, by the clarity of the hue and by good fastness properties.
The subject of the present patent is a process for the preparation of a new dye of the galloeyanin series by condensation of gallic acid with nitrosodisulfo- äthylanilin.
<I> Example: </I> 17 parts by weight of gallic acid are dissolved in 300 parts by weight of 95% alcohol, and 51 parts by weight of nitrosodisulfoethylaniline are added to the solution as the yellow coloration disappears. The dye of the formula:
EMI0002.0001
was cancelled. In the form of its alkali or ammonium salts, it is extremely soluble. Printed on cotton with chrome stain, it gives very even, blue tones of good light, chlorine and soap fastness.
